An ocean monument is a generated structure inhabited by guardian and elder guardian mobs and found in deep oceanic biomes underwater. Built of primarine materials and sea lanterns, monuments are the only place where sponges can be found and one of the two places where prismarine can be found, the other being ocean ruins.
Generation
Ocean monuments generate rarely in areas with deep ocean biome variants within a 16 block square radius around the center point and an aquatic biome (regular/deep/frozen ocean, regular/frozen river) everywhere within a 29 block square radius around the center point. Water generates around the monument as a part of the structure to prevent air pockets. It is the largest structure that does not contain a loot chest and the largest water structure. An ocean monument can also overwrite a stronghold during generation.
Ocean monuments can be located with ocean explorer maps, which are bought from cartographer villagers with emeralds during a trading.
The area of the ocean monument spawns only guardian mobs after generating, also being the only location where guardians spawn. Ocean monuments always contain three elder guardians, one at the top and one in each wing.
Structure
The monument is constructed entirely from variants of prismarine and lit by sea lanterns.
The treasure chamber with a sponge room (smaller dark prismarine room) to its left.
The monument includes a large central section flanked by two wings. Under the monument are 23 giant pillars that stretch to the ocean floor. The main entrance is located at the front of the central section. The base size of the structure is 58×58 blocks. Thus, the ocean monument (the location where guardians and elder guardians spawn) area is 3,364 cubic blocks.
The central section consists of various types of chambers. The chambers are randomly generated; each monument has a different number of rooms (at least six) arranged in a unique manner. The chambers connect vertically and horizontally to the different parts of the monument, including the left and right wings. At the topmost room resides an elder guardian. Around the center of the central section lies the treasure chamber, a tall room with eight gold blocks encased in dark prismarine.
Certain rooms in the monument contain wet sponges.
Monuments may contain one or more rooms with approximately 30 wet sponges on the ceiling sometimes. Sponge rooms have an opening only in the floor and not all monuments generate sponge rooms.
One of the wings contains a large room with a small pillar at the center. The room contains a second elder guardian. The other wing consists of a large open space with a large, square-shaped platform, containing another elder guardian. A long hallway that arcs around the wings and the back portion of the monument connects the two wings together.
